Troy Front Sight; A2 style or HK?

I’m about to buy a set. I just wanted to get some views as to which other users preffered, the A2 or HK style.

From my limited time with HK sights, they seem very open, but there is a familiarity with the A2 ones.

They are going on a flat top with a 10" rail if the extended lenght effects anything.

I like the HK style, lining up the circles seems faster to me.

I have both, and both work fine, but for my next purchase, I’m going to buy another M4 style…just a matter of personal preference.

I have both styles also but don’t really have a preference. They both work fine.

I prefer the M4 style on my AR.

Lining up the two sets of concentric circles can be quick and easy - so quick and easy, that my eyes/brain want to do it every time, which works great unless your front sight post ends up not centered in the front circle after zeroing… In which case I found myself having trouble keeping the post centered properly instead of the the circles. At close range and a quick pace, it was probably a moot point, but it’s still one reason I’ve got Troy version with M4-style “wings” now.

HK

Its quicker…er!

You’re not supposed to “line up the circles”. The troys aren’t true hk style sights… hk sights are adjusted w and e via the rear sight only. On the troys, if your front sight post ends up not centered, you’re in trouble if you wanna “line up the circles”. If you wanna run em that way, buy centurians.

I like the HK-style front. It is very quick to line up and, because I am getting older, I tried a KNS front sight post. That combination really funnels my vision to the target quickly.

I prefer the HK style, but I had one break on me. It was mounted on my carbine and extended. It fell about two feet and hit the floor of my room. One of the wings broke off.

Troy promptly sent me a replacement with no questions asked.

I’ve been messing with HK-style fronts for awhile - I’m just a guy and not an operator, so that that into account.

I find I much prefer having the circle in circle HK-style sight picture over the standard AR wings so long as I have a W and E adjustable rear.

I have a Troy fixed HK style on my 9mm carbine and use a RRA rear, it works well because I simply ignore adjusting the front for elevation and do it all through the rear. I agree with the other comments that moving the front post away from dead center destroys the entire HK sight picture concept, so I personally wouldn’t bother with the Troy rears for this front.

I’d like to give the Centurion diopters a try on this carbine, they have to be lighter than the RRA rear and drum rears have worked well for me in the past.

I’ve found that I am much quicker with HK-style sights than with AR wings, and accuracy doesn’t suffer. I do slightly prefer an open top front like the Troy or Centurion over a closed (full circle) front like on the SIG 556.

Be advised that Centurion’s are a few mm lower that standard AR sights (they are still higher than HK sights) - if you plan on running optics, you have to be careful with mount height selection.

I agree on open top vs. closed top. Closed hood sights take up too much visual space in optics window, provided you’re running front sight up.

The original question has already been answered in this thread multiple times. The circular wings only make sense if sight post is in geometric center of a circle and all adjustments are made via rear.

My preference is the M4 style. I like the look of the Hk style however I try and stick with what I know works for me…

I like the look of the HK better as well (grass is always greener, I suppose). But when I considered that adjusting the front sight post up or down would affect how it was centered, I went with the standard AR/M4 sight. If the sights I looked at were true HK style, I might have changed my decision.

I’m struggling to see how the front sight post moving up or down makes the slightest difference. If you line up the circles, the point of impact and point of aim should be the top of the front sight post. Keep in mind this isn’t a thread about holdover…

Now if the gun was shooting high or low, the front sight post would be raised or lowered. This has nothing to do with how you line up the circles. The only thing that changes is where the front sight post is within that circle. If you are topping out the front sight post to zero it, you have a mechanical problem or shooter error somewhere. Zero adjustments should never be that far off…

I thought the same thing at first so I raised the front sight post. I found I constantly sighted low and had to consciously adjust my aim - my brain wanted to line up the circle in the circle with the target dead center. Yes, you can overcome it - but it slowed me down. YMMV.

Nope, it doesn’t work that way. Most of the time you’d need to move front sight post up or down few turns. You need to keep it centered of rear sight aperture; you really don’t care about relationship to sight’s ears, be it HK or M4 style.
With my HK-styled Troys, the 50/220 yard zero required me to lower front sight post 2 turns. With that, obtaining correct sight picture (front sight post in the center of rear sight aperture) lead to “misalignment” of front and rear circles ( front sight circle displaced up). Conversely aligning those two would position the front sight tip low in rear sight aperture. I hope I am explaining this clear enough, or I misunderstanding you in some way.

Deleted – badly misread something.

I would consider a correct sight picture to be circles lined up and the tip of the post poa/poi. If its higher or lower than the dead center of the circle than so be it, it’s not a red dot.

I don’t see how the front sight post being low in the rear sight aperture is a problem. It is way easier to judge if the circles are aligned than if the post is centered. I’ve never centered a front sight post within a rear the way you are describing.

With a A2 style sight, ears aligned on the circle and what I want to shoot on the tip of the front sight post. I’ve never heard of it being required to center the tip of the front sight post in the rear arp. I’ve never heard this point of view before. With true HK sights, the front sight post would always be centered, but the hybrid troy M16/HK doesn’t work the same.

This makes me want to buy the HKs just to try it out…

The idea is not that the tip of the post must be located in the geometric center of the circles. The concept is that you would align the circles to index the front sight and then place the post where you want it. Placing the tip of the post on your target is faster than trying to make sure both circles are exactly aligned. There are better sight options for precision shooting. For me, the value of the HK style is quickly hitting man-size targets in center mass.
